We’ve been discovering how to write performant JavaScript in Node.js since the beginning. Before we knew how it was it done it all seemed so magical. But as we became better at understanding fast-scrolling text littered with hex addresses we began a journey to solidify our approach and share it with others. Our primary strategy? Build tools that make optimizing Node easier, then formalize a workflow process around those tools. The workshop is extremely interactive. We make sure that each participant solves several performance issues in a given HTTP application. Our methods and tools include 0x for flamegraph generation, autocannon for HTTP/1.1 benchmarking, v8 trace analysis, and bytecode interpretation all within a structured analysis workflow.
Requirements: Participation requires a recent version of either Linux, Windows or macOs. You will need root/admin access, and the ability to build native node modules (XCode and command line tools on Mac OS X, Visual Studio on Windows).
